The article presents a study and a quantitative analysis of nail polish remover using a nuclear magnetic resonance spectroscopy. The experiment was done by a group of students who used the method of standard addition, instead of internal standard, for the analytical procedure. The analytes of the study were ethyl acetate, 2-propanol, and acetone. Description and discussion of the experiment undertaken are provided in the article. Technical and logistical details are also offered along with the results of the study.

The article cites an experiment which involves calibration of the maximum magnetic field gradient strength through obtaining a series of projection images from several phantom objects as a function of applied field gradient strength to illustrate magnetic resonance imaging (MRI). A regular nuclear magnetic resonance (NMR) spectrum without gradients has been required to determine the effect of the gradients. From the same sample, an application of the magnetic field gradient gradient is also considered as part of the pulse program. The authors also shed light on the effect of linear gradients in NMR spectroscopy.

The application of supercritical (sc) fluid technology requires a thorough understanding of thermodynamic phase behavior. Therefore, an experiment in the physical chemistry laboratory that allows direct control and visual observation of P-V-T phase behavior has educational value for students. Students develop an experience-based understanding of how phase behavior can be manipulated. Laboratory experiments involving sc fluids also provide valuable training for students concerning the proper and safe handling of compressed fluids.

The objective of this article is to communicate and discuss a classroom exercise that engages students as a team to develop an intuitive understanding of the P- V- T phase behavior of a pure fluid. The classroom exercise requires the availability of four one-half hour periods. Since the exercise draws on the students' visualization and imagination skills, each period is actually a rather intense experience and should probably not exceed the half-hour period by too much. The author hopes to have stimulated the reader to further think about how to best confront the students with this challenging thermodynamic subject and how to best guide them through the learning process.

The article offers information about the experiment that incorporates nuclear magnetic resonance spectroscopy for measuring ternary phase diagrams. Prior to the formulation of this experiment was the growing need to additionally incorporate experiments that employ modern experimental techniques in the area of spectroscopy. In order keep the viability of the ternary phase diagram experiments, modifications were made to promote more safety. This experiment is a modification which employ the Hydrogen Nuclear Magnetic Resonance Spectroscopy in the ternary phase diagram experiment. This experiment supplements general phase behavior discussions in the undergraduate curriculum of physical chemistry.
